An additional waste discharges included in this Fact Sheet and prohibited in Order No. R9-2002-0169 are the discharges associated with:

• Ship repair and maintenance activities.

The additional discharge is based on the information contained in the Regional Board’sadministrative records. The administrative records include inspection reports for the Navycomplexes in San Diego; Notice of Violation (NOV) No. 2000-118, dated May 24, 2000, issuedto the Navy for paint chip discharges from the USS Essex; and industrial storm water annualmonitoring reports for NAVSTA, and commercial shipyards in San Diego (i.e. National Steel &Ship Building Co., SouthWest Marine, and Continental Maritime).

The diverse discharges from ship repair and maintenance activities could occur at severallocations, including aboard ship when docked, on the piers, or on shore locations. Ship repairand maintenance activities include abrasive blasting, hydroblasting, metal grinding, painting,tank cleaning, removal of bilge and ballast water, removal of anti-fouling paint, sheet metalwork, electrical work, mechanical repair, engine repair, hull repair, and sewage disposal.

The ship repair and maintenance activities may be conducted by Navy personnel (ships’ force),civil service personnel, or civilian contractors. Berth side maintenance on the surface ships,support vessels or barges may include all of the activities listed in the first paragraph describingthe ship repair activities. Berth side ship repair activities are generally less complex than the shiprepair activities conducted at a shipyard. Ship repair activities may also be conducted on thepiers. Boats, ship sections, or parts can be placed on the piers or adjacent lands for repairs.

Another point source discharge form the NBSD are industrial storm water discharges. Theindustrial storm water discharges will be regulated by this Order.

On June 27, 2002, the CNRSW submitted a Report of Waste Discharge (RWD) for a NationalPollutant Discharge Elimination System (NPDES) permit for the NBSD Complex. Theadministrative file for this Fact Sheet and for Order No. R9-2002-0169 contains the RWD datedJune 27, 2002. Over the past several years, the Navy has submitted various RWDs for NPDESpermits for the different Naval Base operations in the San Diego Region. Order No. R9-2002-0169, NPDES Permit No. CA0109169 is the second NPDES permit developed for a completeNaval Base Complex operation in the San Diego area.

The first NPDES permit for a complete Naval Base Complex is Order No. R9-2002-0002,NPDES Permit No. CA0109363, for the Naval Base Point Loma (NBPL), which was adopted atthe Regional Board’s October 9, 2002 meeting.

The Graving Dock facility at the 32nd Street Naval Facility is regulated by Order No. 98-53,NPDES Permit No. CA0107867. Even though the Graving Dock is located in the NBSDComplex, the Graving Dock facility will continue to be regulated by Order No. 98-53, a separateNPDES permit.

I. FACILITY DESCRIPTIONS

This Fact Sheet is for Order No. R9-2002-0169, which will regulate the discharges from theinstallations included as part of the NBSD Complex. The NBSD Complex includes the Navyinstallations listed below:

• Naval Station, San Diego (NAVSTA);• Mission Gorge Recreational Facility (MGRF);• Broadway Complex; and• Naval Medical Center, San Diego (NMCSD).

A location map showing the different NBSD installations is attached to this Fact Sheet asAttachment A.

a. Naval Station, San Diego (NAVSTA)

Installation Location and Description

The NAVSTA is located on the eastern edge of San Diego Bay, bordered by the cities of SanDiego to the north and east and National City to the south and east. The NAVSTA is about threemiles southeast of downtown San Diego and 10 miles north of the Mexican border. TheNAVSTA is a large facility located within three Hydrologic Subareas, the Chollas HydrologicSubarea (908.22) of the San Diego Mesa Hydrologic Area (908.20); and the El ToyanHydrologic Subarea (908.31), and the Paradise Hydrologic Subarea (908.32) of the NationalCity Hydrologic Area (908.30). The three Hydrologic Subareas are in the Pueblo San DiegoHydrologic Unit (908.00).

The NAVSTA is the largest installation within the three major naval base complexes. It hasmore ships, personnel, and support operations. The activities are organized in 21 operationaldepartments, special assistants, and staff offices under the Commanding and Executive Officers.The central location of NAVSTA within the three major naval base complexes is an advantagefor the coordination of joint operations and the functioning of regional service centers. There areover 45 tenant activities aboard the station, including major commands such as Fleet TrainingCenter (FTC); Navy Public Works Center (PWC); Supervisor of Shipbuilding, Conversion, andRepair (SUPSHIP); Shore Intermediate Maintenance Activity (SIMA); and the Naval SupplyCenter (NSC). Personnel support activities at NAVSTA include the Regional CommissaryStore; Naval Dental and Medical Clinics; Naval Legal Service Office; Trial Judiciary;Environmental Preventative Medicine Unit Five; Personnel Support Detachment; and NavyResale and Service Support Office.


4 November 13, 2002

The mission of NAVSTA is to provide appropriate logistical support for the operating forces ofthe U.S. Navy and for dependent activities and other commands as assigned. The NAVSTAforms the major west coast logistic base for surface operating forces of the U.S. Navy and fordependent activities and other commands. The NAVSTA is homeport to 55 Pacific Fleet shipsand has in-port berthing requirements for 56 Surface Force ships and 51 service craft assigned tothe NAVSTA, NSC, and PWC.

The NAVSTA occupies 1,049 acres of land and water at a site lying east and west of HarborDrive. The wetside consists of the Bay front area west of Harbor Drive. The dryside consists ofthe community facilities complex east of Harbor Drive.

The wetside is intensively developed and supports waterfront operations, ship berthing andmaintenance, station maintenance, training, administration, and logistics functions. Operationalfacilities include piers, quay walls, small craft berthing facilities, fueling facilities, armories, andwaterfront operations buildings. The straight-line map measurement of the shoreline atNAVSTA is 1.6 miles. The NAVSTA contains 13 berthing piers, a mole pier, two channels, andvarious quay walls that have a total shoreline measurement of approximately 5.6 miles.

The 13 piers at NAVSTA are utilized to berth surface ships, support vessels, and barges. Thesurface ships, support vessels, and barges receive various ship support services such as suppliesand minor repair or maintenance when berthed. Ship support services on the 13 piers includeloading supplies and equipment onto the ships. Berth side ship repair and maintenance (that is,maintenance while the vessel is docked at the pier) may include abrasive blasting, hydro-blasting,metal grinding, painting, tank cleaning, removal of bilge and ballast water, removal of anti-fouling paint, sheet metal work, electrical work, mechanical repair, engine repair, hull repair, andsewage disposal. Berth side ship repair activities are generally less complex than the ship repairactivities conducted at commercial shipyards or at the Navy’s graving dock or floating drydock.Berth side maintenance may be conducted by Naval personnel (ships’ force), civil servicepersonnel, or civilian contractors.

Ship repair activities may also be conducted on the piers. Boats, ship sections, or parts can beplaced on the piers or adjacent lands for repairs. The ship repair activities may be conducted byNavy personnel (ships’ force), civil service personnel, or by civilian contractors. The breadth ofwork performed by the civilian contractors is typically greater than the work performed by ships’force. Most of the more complex ship repair work is conducted on ships berthed at Pier 13.Typically, civilian contractors will store materials and supplies on Pier 13 while working aboardthe ship berthed at the Pier. However, ship repair activity is not limited to ships berthed at Pier13. The NAVSTA also has several SIMA repair shops at the facility. The SIMA repair shopsconduct repairs on various parts of the vessels, such as antenna repair or mechanical repairs.

Two land parcels within the NAVSTA perimeter are not under the control of NAVSTA. A 25.8-acre compound is owned by Naval Supply Center, and 40 acres of railroad right-of-way is ownedby the Atchison, Topeka & Santa Fe Railroad (AT&SF) and the Metropolitan TransitDevelopment Board (MTDB). Interstate 5, Harbor Drive, and various public utilities occupy


5 November 13, 2002

54.51 acres of NAVSTA real estate under easement or permit. There are no discharges reportedas being associated with the land parcels not under the control of NAVSTA. Storm Water DischargesThe industrial storm water discharges from the NAVSTA are currently regulated by the StateWater Resources Control Board (State Water Board), Water Quality Order No. 97-03-DWQ,National Pollutant Discharge Elimination System (NPDES), General Permit No. CAS000001(General Permit), Waste Discharge Requirement (WDR) for Discharges of Storm WaterAssociated with Industrial Activities Excluding Construction Activities (General Industrial StormWater Permit), WDID 937S002275. After the adoption of the Order, enrollment pursuant toOrder No. 97-03-DWQ will be superseded.

All industrial storm water discharges will be regulated by this Order. There are highconcentrations of copper and zinc in the industrial storm water discharges from the NAVSTA.Therefore, effluent limitations for toxicity are included in the Order. Additional informationregarding the industrial storm water discharges at NAVSTA is included in the Storm WaterDischarge section of this Fact Sheet.

Point Source DischargesPoint source discharges (ship repair and maintenance activities, steam condensate, salt watersystem, pier boom, mooring and fender cleaning, utility vault & manhole dewatering, andmiscellaneous discharges) from the NAVSTA are described in the Point Source Dischargesection of this Fact Sheet. The Point Source Discharge section describes those dischargesidentified by the CNSRW in its NPDES application or identified by the Regional Board duringinspections of the NBSD Complex.

b. Mission Gorge Recreational Facility (MGRF)


The MGRF is located in the City of San Diego along the San Diego River and is within theMission San Diego Hydrologic Subarea (907.11) of the Lower San Diego Hydrologic Area(907.10) of the San Diego Hydrologic Unit (907.00). The MGRF is a 440-acre facility locatedeast of Interstate 15, north of Friars Road, and west of Mission Gorge Road. The MGRF iscommonly known as Admiral Baker Field. The primary mission of MGRF is to provide formaximum participation in programs that are designed to enhance physical, mental, and socialhealth of all active duty personnel and their dependents.

The majority of the land use at MGRF consists of two 18-hole golf courses and a driving range.Support facilities include a dance pavilion, snack bar, and coffee shop. Other recreationalfacilities include tennis courts, volleyball courts, a swimming pool, baseball fields, and arecreation vehicle (RV) camping area located on the southwestern edge of MGRF. The facilityconsists of cultivated and landscaped habitat with various ornamental trees and shrubs planted on

the golf course and surrounding areas. Natural habitat includes woodland along the San DiegoRiver and coastal sage scrub adjacent to the golf course and on steep slopes.

Storm Water DischargesStorm water discharges from the MGRF are considered to be non-industrial and are not regulatedby the General Industrial Storm Water Permit or by this Order. The MGRF will be subject toregulation by the Phase II municipal storm water regulations in March 2003.

Point Source DischargesThere are no identified point source discharges at the MGRF.

c. Broadway Complex


The Broadway Complex is located in downtown San Diego at 937 North Harbor Drive on thecorner of North Harbor Drive and Broadway. The Broadway Complex is within the LindberghHydrologic Subarea (908.21) of the San Diego Mesa Hydrologic Area (908.20) of the PuebloSan Diego Hydrologic Unit (908.00).

The commands located at this facility include the offices of Commander, Navy RegionSouthwest, Personnel Support Activity, Navy Computer & Telecommunications Station, ReserveReadiness Command, and Fleet and Industrial Supply Center. Historically this facility served asa supply depot, but it has operated only minimally in that capacity since the middle 1990s.

Storm Water DischargesThe industrial storm water discharges from the Broadway Complex are currently regulated by theGeneral Industrial Storm Water Permit, WDID 937S001987. All industrial storm waterdischarges from the Broadway Complex will be regulated by this Order. After the adoption ofthe Order, enrollment pursuant to Order No. 97-03-DWQ will be superseded.

Point Source DischargesThe point source discharges (landscape runoff, potable water and fire system maintenance) aredescribed in the Point Source Discharge section of this report. The Point Source Dischargesection describes those discharges identified by the CNRSW in its NPDES application.

d. Naval Medical Center San Diego (NMCSD)


The NMCSD is located within Balboa Park and occupies 79 acres in Florida Canyon. TheNMCSD is within the Lindbergh Hydrologic Subarea (908.21) of the San Diego MesaHydrologic Area (908.20) of the Pueblo San Diego Hydrologic Unit (908.00).The hospital complex contains 500,000 square feet and provides service to approximately 3,800patients on an average day.

The NMCSD provides medical care to active duty personnel, their dependents, and retirees. Thehospital is one of only two teaching hospitals in the Navy. It provides training for enlistedhospital corpsmen and junior medical officers and nurses. The Medical Center Commander isalso responsible for all Navy and Marine Corps medical facilities in California, Nevada, andArizona.

Storm Water DischargesThe General Industrial Storm Water Permit currently regulates the industrial storm waterdischarges from the NMCSD, WDID 937S 0001933. All industrial storm water discharges fromthe NMCSD will be regulated by the Order and enrollment pursuant to Order No. 97-03-DWQwill be superseded. The U.S. Navy comment letter dated October 29, 2002, the Regional Boardwas informed that the NMCSD has submitted a Notice of Termination for its industrial stormwater discharges subject to regulation by the General Industrial Storm Water Permit.Subsequently an errata sheet for Order R9-2002-0169 included the deletion of the NMCSD as anindustrial discharge regulated by the Order.

Storm water discharges from the NMCSD are considered to be non-industrial and are notregulated by the General Industrial Storm Water Permit or by this Order. The NMCSD will besubject to regulation by the Phase II municipal storm water regulations in March 2003.

Point Source DischargesThe point source discharges (landscape runoff, potable water and fire system maintenance) aredescribed in the Point Source Discharge section of this report. The Point Source Dischargesection describes those discharges identified by the CNSWR in its NPDES application.

II. POINT SOURCE DISCHARGES

The point source discharges identified in the RWD are grouped into five general industrialprocesses:

• Utility Vault & Manhole Dewatering;• Steam Condensate;


8 November 13, 2002

• Salt Water System Discharge;• Pier Boom, Mooring, and Fender System Cleaning; and• Miscellaneous Discharges (landscape watering runoff, potable water & fire system

maintenance).

Latitude and longitude coordinates for Point Source discharges were included in the RWD. Thelatitude and longitude coordinates and maps identifying the discharge locations are included inAttachment B of this Fact Sheet.

Additional waste discharges included in this Fact Sheet and prohibited in Order No. R9-2002-0169 are the discharges associated with:

• Ship repair and maintenance activities.

The additional discharge is based on the information contained in the Regional Board’sadministrative records. The administrative records include inspection reports for the Navycomplexes in San Diego; Notice of Violation (NOV) No. 2000-118, dated May 24, 2000, issuedto the Navy for paint chip discharges from the USS Essex; and industrial storm water annualmonitoring reports for NAVSTA, and commercial shipyards in San Diego (i.e. National Steel &Ship Building Co., SouthWest Marine, and Continental Maritime).

The diverse discharges from ship repair and maintenance activities could occur at severallocations, including aboard ship when docked, on the piers, or on shore locations.

Descriptions of the waste discharges from the NBSD are provided below. The descriptions aretaken from information in the administrative record as explained above and in the RWDsubmitted by the Navy.

a. Ship Repair and Maintenance Activities

Ship repair and maintenance activities include abrasive blasting, hydroblasting, metal grinding,painting, tank cleaning, removal of bilge and ballast water, removal of anti-fouling paint, sheetmetal work, electrical work, mechanical repair, engine repair, hull repair, and sewage disposal.

The ship repair and maintenance activities may be conducted by Navy personnel (ships’ force),civil service personnel, or civilian contractors. The specifications, prohibitions, and monitoringrequirements in Order No. R9-2002-0169 apply to all ship repair and maintenance activities atNBSD conducted under the control of the U.S. Navy.

Berth side maintenance on the surface ships, support vessels or barges may include all of theactivities listed above. Berth side ship repair activities are generally less complex than the shiprepair activities conducted at a shipyard. Ship repair activities may also be conducted on thepiers. Boats, ship sections, or parts can be placed on the piers or adjacent lands for repairs.


9 November 13, 2002

At NAVSTA, Pier 13 is used for the more significant ship repair and maintenance work, and theother piers may also have less complex ship repair or maintenance work.

Prohibited discharges—Ship repair and maintenance activities result or have the potential toresult in discharges to San Diego Bay of wastes and pollutants which are likely to cause orthreaten to cause pollution, contamination, or nuisance; adversely impact human health or theenvironment; cause or contribute to violation of an applicable water quality objective; orotherwise adversely affect the water quality or beneficial uses of waters of the state and waters ofthe United States. Such discharges include the following:

• water contaminated with abrasive blast materials, paint, oils, fuels, lubricants,solvents, or petroleum;

• hydroblast water;• tank cleaning water from tank cleaning to remove sludge and/or dirt;• clarified water from oil/water separator;• steam cleaning water;• demineralizer and reverse osmosis brine;• oily bilge water;• vessel washdown water;• floating drydock submergence and emergence water;• pipe and tank hydrostatic test water;• miscellaneous low-volume water;• saltbox water;• paint chips;• paint over spray;• paint spills;• hydraulic oil leaks and spills;• fuel leaks and spills;• abrasive blast materials;• trash;• miscellaneous refuse and rubbish;• fiberglass dust;• swept materials; and• ship repair and maintenance activity debris.

Information regarding the industrial storm water discharges associated with the ship repair andmaintenance activities is included in the Industrial Storm Water Discharges section forNAVSTA.


10 November 13, 2002

b. Utility Vault & Manhole Dewatering

The NBSD has electrical and steam utility vaults and manholes that may discharge wastes tosurface waters. Utility companies, or agencies, such as the Public Works Center (PWC) for theNBSD, supply resources, excluding water, as necessary for day-to-day living and operations.This includes, but is not limited to supplies of natural gas, electricity, and telephone service.Electrical and steam utilities are owned and maintained by the PWC. The utility vault dischargesare short-term intermittent discharges of pollutants from utility vaults and undergroundstructures.

Typically, utility companies must de-water the vaults and underground structures prior toperforming any repair, maintenance and/or installation of equipment, for safety reasons. Water ispumped from the vaults or structures when the volume of water interferes with the safety orquality of the work to be done. The volume of discharge could vary from a few gallons tothousands of gallons. The duration of discharge and pump rates for the discharge could also varygreatly.

Navy installations in San Diego require electrical power for both shore and afloat operations.The on-base electrical power is carried through an extensive underground conduit system.Electrical utility vaults and manholes contain high voltage electrical equipment, transformers,switchgear, and/or below grade cables.

The steam utility manholes can also accumulate steam condensate water. High-pressure steamlines are also located in underground conduit systems and are accessed through utility manholes.

There are 15 electrical vaults located at NAVSTA that can have point source discharges. Threeof the 15 vaults are located under Pier 2. The pier vaults are subject to Bay water intrusion andcan also accumulate storm water during rain events. Automatic sump pumps are installed in eachvault and discharge the accumulated water directly to San Diego Bay.

The remaining 12 vaults are located on land, and inside buildings, and are associated withelectrical switching or substations. Similar to the pier vaults, the vaults on land can alsoaccumulate ground water and storm water and are dewatered using automatic sump pumps. Thesump pumps discharge the water on to the ground surface around the vault building. Dependingon the discharge volume these discharges could reach a storm drain inlet and discharge to SanDiego Bay.

In addition to the vaults, electrical and steam utility manholes are located on all of the NBSDinstallations except at the MGRF. Both the electrical and steam utility manholes can accumulategroundwater and storm water that must be removed when maintenance or emergency work isrequired.

All manholes at the NBSD are manually dewatered using a portable pump or pump truck. Forover two years PWC has implemented procedures to eliminate manhole dewatering discharges tosurface waters. PWC either pumps the water into an adjacent utility manhole or transfers the



water to the sanitary sewer system. Although there could be an emergency situation that wouldrequire dewatering a manhole onto the ground surface, PWC has not had to do this in over twoyears.

The discharges from the NBSD electrical utility vaults and manholes are regulated by CaliforniaState Water Resources Control Board, Water Quality Order No. 96-12-DWQ, Statewide GeneralNational Pollutant Discharge Elimination System (NPDES) Permit for Discharges from UtilityVaults and Underground Structure to Surface Waters, General Permit No. CAG990002, WasteDischarge Requirements (General Utility Vault Permit), WDID 9000U000058. On July 19, 2001the State Board adopted Order No. 2001-11-DWQ to supersede Order No. 96-12-DWQ. As ofSeptember 26, 2002 the USEPA as not approved Order No. 2001-11-DWQ. After the adoptionof the Order, enrollment pursuant to Order No. 96-12-DWQ will be superseded.

In accordance with the General Utility Vault Permit, the PWC has developed pollutionprevention practices for utility vault and manhole discharges. The pollution prevention practicesinclude inspections of utility vaults and manholes for potential pollutant sources and thedewatering of utility manholes into adjacent utility manholes or the sanitary sewer system. Acase study was performed during the 2001/2002 wet season to characterize any discharges fromthe utility vaults and manholes.

Order No. R9-2002-0169 incorporates the pertinent specifications, limitations, and monitoringrequirements of the General Utility Vault Permit (Order No. 2001-11-DWQ). By including thedischarges from the Utility Vaults and Manhole Dewatering in the Order, the NBSD will haveone NPDES permit for all of its surface water discharges except for discharges from the GravingDock, which is regulated pursuant to Order No. 98-53, CA0109363, and any discharges regulatedpursuant to Order No. R9-2002-0020, NPDES No. CAG6790001 (i.e., Hydrostatic Test Waterand Potable Water discharges) or other applicable NPDES permits.

The State Board, in Finding 13 of the General Utility Vault Permit (Order No. 2001-11-DWQ),granted the utility vault discharges an exception to Sections 1.3 and 1.4 of the Policy forImplementation of Toxic Standards for Inland Surface Waters, Enclosed Bays, and Estuaries ofCalifornia (Implementation Policy) because numeric effluent limits are infeasible for dischargesfrom vaults and underground structures.

This Order does not require monitoring of the Utility Vault and Manhole Dewatering dischargespursuant to the requirements in the Implementation Policy. If the USEPA does not approveOrder No. 2001-11-DWQ, the Order may need to be revised to include monitoring pursuant tothe Implementation Policy.

MRP No. R9-2002-0169 includes monitoring for chemicals, and requires the submittal of a logof the discharges to identify any potential impacts to beneficial uses.



c. Steam Condensate

The U.S. Navy uses a pressurized steam system for both shore and afloat operations. WithinNBSD, only the NAVSTA has an on-base steam system. The steam system at NAVSTAproduces a steam condensate that is discharged to San Diego Bay.

Steam is produced at NAVSTA by an on-site cogeneration plant that is operated by Sithe Energy,a Navy contractor. During the production of steam, chemicals are injected into the boiler feedwater or directly into boilers. The following chemicals are injected during steam production:

• Trident 1202 (into boiler),• Trident 3506 (into boiler feed water),• Trident 2301 (into boiler feed water),• Trident 1003 (into boiler), and• Trident 1103 (into boiler).

Only the Trident 3506 and Trident 2301 leave the boiler and can be present in the steamcondensate. Copies of the Material Safety Data Sheets for each of the chemicals and a flowdiagram showing the steam generation process were included in the RWD.

After leaving the plant, the steam enters the distribution system, which consists of high and lowpressure steam lines; pressure reducing valve stations; and expansion joints. The steam isprovided to buildings and surface ships. The steam system has traps in the steam lines designedto discharge steam condensate to ensure the steam supplied to users meets quality assurancespecifications and is free of condensate. When water collects in the steam lines it is essential forthe system to remove the water as soon as possible.

There are 190 steam condensate discharge points at NAVSTA and all but two are located on thepiers or along the quay wall. The pier discharge points, in addition to releasing steam, drip smallamounts of water to the Bay between steam discharges. The estimated discharge rate for thesteam lines is one ounce per minute. The total discharge volume per day for the 188 dischargepoints is approximately 2,150 gallons per day.

The steam condensate discharges from NBSD are typically steam condensate from traps. Thesteam discharges are typically a cloud of steam that has a temperature in excess of 100o Celsius.A portion of the steam evaporates prior to condensing and discharging to the Bay or groundsurface depending on the location of the steam trap.

As shown in Table 1. through Table 4. Steam Condensate Discharge Analyses, . . . the NPDESapplication included laboratory analyses for the steam condensate discharges from the identifiedlocations. Because the reported chemical concentrations in the discharge are low and thedischarge flow rates are low, the Steam Condensate discharges are not a significant threat towater quality.

Any steam condensate discharged from a vault or manhole is regulated as a utility vault dischargeas described in the previous section on utility vaults.

The low volume steam discharges are subject to regulations pursuant to the ImplementationPolicy. MRP No. R9-2002-0169 requires monitoring for evaluating compliance with theImplementation Policy.



MRP No. R9-2002-0169 requires annual monitoring of the steam condensate discharge forcertain chemicals to monitor the quality of the discharge and to evaluate potential impacts towater quality.

d. Salt Water SystemNota Bene: Pursuant to comment letter from the U.S. Navy dated October 29, 2002, the SaltWater System on the Mole pier has been shut down. Information regarding flow rates were notincluded in the comment letter.

The salt water system pumps San Diego Bay water from Pier 13 to the Graving Dock Facilitylocated between Piers 5 and 6. The NAVSTA salt water system provides pressurized Bay waterfor fire fighting water and for cooling water to the ships being repaired in the Graving Dock. Thesalt water system is a deadhead system, that is, there is no return line. Unused water in thesystem will discharge through a pressure relief valve to the Bay.

The Order regulates the discharges from the salt water system pressure relief valves located atPier 13 and the Mole Pier at NAVSTA. The combined maximum discharge rate for both reliefvalves is 1,000 gallons per minute. During calendar year 2001, this system operated for 45 days.The system runs 24 hours a day during periods of demand. The total discharge for 2001 wasapproximately 64.8 million gallons.

The salt water system discharges that occur at the Graving Dock Facility are regulated by WDROrder No. 98-53, NPDES Permit No. CA0107867, and will not be regulated pursuant to thisOrder. The Navy plans to install a separate salt water pumping station at the Graving Dockwithin the next year. When the salt water system pumping station is installed at the GravingDock, the pumps at Pier 13 will be deactivated and the discharges from Pier 13 and the Mole Pierwill cease. The salt water discharges at the Graving Dock will continue to be regulated by OrderNo. 98-53, NPDES Permit No. CA0107867.

Pollutants that may be found in the salt water discharge include:

• contaminants in the seawater supply to the pumps; and• any contaminants that the water comes into contact with as it circulates through the

system.

The RWD included an analyses for metals, TPH diesel, and temperature. The laboratory analysisis shown in Table 5. Salt Water System Discharge Analyses, Mole Pier, and Pier 13. Allsamples collected were grab samples. Because the reported chemical concentrations in thedischarge are low and the discharge flows are intermittent, the Salt Water System discharges arenot a significant threat to water quality.

e. Pier Boom, Mooring, and Fender System Cleaning

Security booms, oil containment booms and fender systems are placed around vessels and piersat NAVSTA. The security and oil containment booms placed around the vessels and piers, andthe pier mooring and fender systems have marine growth on them. The marine growth can causethe booms, moorings, and fender systems to sink. The marine growth is washed off with high-pressure potable water. The booms, mooring, and fender systems are not removed from thewater during the cleaning process.

Typically, booms, moorings, and fender systems are cleaned twice per year on a quarterlyrotational basis. The high-pressure washer discharges 5 gpm and operates six hours/day for 2-3weeks per quarter for at total annual discharge of approximately 0.108 million gallons.



After a response to an oil spill, the oily booms are removed from the Bay by barge andtransported to a designated cleaning area at the NAVSTA for cleaning. The cleaning water fromthe designated cleaning area discharges to the bilge and oily water treatment system (BOWTS)and then to the sanitary sewer system.

The discharge of high-pressure wash water for boom, mooring, and fender system cleaning couldbe subject to regulations in the Implementation Policy. MRP No. R9-2002-0169 requiresmonitoring for evaluating compliance with the Implementation Policy.

An annual reporting log of boom, mooring and fender system cleaning activity and the removalof any oily booms for cleaning is required by the Order.

f. Miscellaneous

The following miscellaneous discharges can occur at the NBSD Complex:

! Fire hydrant flushing;! Fire suppression sprinkler system flushing;! Potable water system operation, maintenance, and testing;! Emergency eye wash/shower station maintenance;! Air conditioner condensate; and! Landscape watering.

Fire Hydrant FlushingFire hydrants are periodically flushed to remove stagnant water in the line to ensure that theproper chlorine residual is maintained in the distribution system. Hydrants are also flushed whenmaintenance on valves is conducted; when tests to determine hydraulic pressure and flow ratesare performed; and when any rust or sediment in the line requires removal.

Fire Suppression Sprinkler System FlushingRecurring maintenance of building fire suppression sprinkler systems includes draining andflushing the sprinkler piping to remove stagnant water; inspection and maintenance of the valves,sprinkler heads, and manual actuators, and alarm infrastructure.

Potable Water System Operation, Maintenance, and TestingAs part of the Navy’s backflow prevention and water system maintenance programs, backflowprevention assemblies and other potable water equipment must be tested and maintained on aregular basis. Discharges of potable water may occur during testing and maintenance.

Emergency Eye Wash/Shower Station MaintenanceProper maintenance of the emergency eye wash/shower station is essential for maintaining a safework environment. Eye wash/shower stations are flushed when maintenance is conducted.



Water released from the station during maintenance is discharged to the ground and has thepotential to enter the storm drain system.

Air Conditioner CondensateAir conditioners are located throughout the NBSD Navy installations and are used forenvironment and equipment cooling. Condensate is regularly discharged from air conditioners,however, most discharges are at an extremely low flow rate.

Landscape WateringLandscape watering constitutes a significant portion of the potable water usage on Navyinstallations. Runoff from landscape water can flow into the storm drain system or directly intoSan Diego Bay.

Best Management Practices have been developed to reduce or eliminated pollutants in thesedischarges. The discharges identified above could be subject to regulations in theImplementation Policy. MRP No. R9-2002-0169 requires monitoring for evaluating compliancewith the Implementation Policy provided the miscellaneous discharge is not regulated pursuant toOrder No. R9-2002-0020, NPDES No. CAG6790001 (i.e., Hydrostatic Test Water and PotableWater discharges) or other applicable NPDES permits.

Annual reporting of any significant changes in these discharges is required by the MRP.

III. INDUSTRIAL STORM WATER DISCHARGES

The NBSD Complex includes four Navy installations. The Navy submitted Notices of Intent(NOIs) to comply with the State Water Resources Control Board (State Water Board), WaterQuality Order No. 97-03-DWQ, National Pollutant Discharge Elimination System (NPDES),General Permit No. CAS000001 (General Permit), Waste Discharge Requirements forDischarges of Storm Water Associated with Industrial Activities Excluding ConstructionActivities (General Industrial Storm Water Permit) for three of the four installations. TheGeneral Industrial Storm Water Permit establishes NPDES waste discharge requirements forindustrial storm water discharges and requires the discharger to develop and implement a StormWater Pollution Prevention Plan (SWPPP) and a Monitoring and Reporting Program.

Storm water discharges from the Mission Gorge Recreational Facility (MGRF) are non-industrial. The MGRF does not have facilities or operations requiring regulation by an IndustrialStorm Water Permit.

The municipal storm water discharges from the NBSD will be subject to regulation by theRegional Board in March 2003. The municipal storm water discharges may be regulated by the



current San Diego County municipal storm water permit, or may be regulated by a separatemunicipal permit.

Upon adoption, the Order will supersede the General Industrial Storm Water permit. Industrialstorm water discharges occur from the following three Installations:

a. Naval Station, San Diego (NAVSTA)

There are 56 outfalls identified as industrial storm water outfalls at NAVSTA. Twenty-two ofthe 56 outfalls were sampled pursuant to the General Industrial Storm Water Permit, WDID937S002275. The NAVSTA developed and has implemented an industrial storm water pollutionprevention plan and a monitoring program since 1994.

b. Broadway Complex

There are three outfalls identified as industrial storm water outfalls at the Broadway Complex.Two of the three outfalls were sampled pursuant to the General Industrial Storm Water Permit,WDID 937S001987.

c. Naval Medical Center, San Diego (NMCSD)

There are two outfalls identified as industrial storm water outfalls at the NMCSD, WDID937S001933. NMCSD has implemented a storm water pollution prevention plan and monitoringprogram since 1994. Nota Bene: The industrial storm water discharges at NMCSD have beenterminated and will not be subject to regulation by this Order (See page 7 of this Fact Sheet).

d. Storm Water Working Group

To improve the Navy’s storm water management program in the San Diego area, CNRSW hasformed a Storm Water Working Group (SWWG). The SWWG meets on a quarterly basis todiscuss storm water issues. The SWWG membership includes a wide spectrum of Navyactivities including personnel associated with environmental compliance, port operations, facilitymaintenance, ship support services, ship operations, facility planning and others. Through theSWWG, the Navy has developed a storm water geographic information system (GIS) for all ofthe bases in San Diego covered by the General Industrial Storm Water Permit. The SWWG isalso testing the use of new BMP such as storm water filtration systems, and mechanical sweepersand scrubbers.

CNRSW has surveyed the storm water conveyance systems associated with industrial stormwater discharges to identify illicit connections. The surveys included dye and smoke testing, and



the use of video cameras. Based on those surveys, all known illicit connections have beeneliminated.

e. Multi-Sector Permit and Industrial Storm Water Monitoring Data

The USEPA has adopted a general industrial storm water permit for various industrial facilitiesunder its jurisdiction. The USEPA permit, the Final Reissuance of National Pollutant DischargeElimination System (NPDES) Storm Water, Multi-Sector General Permit for Industrial Activities,Federal Register, Monday, October 30, 2000, (Multi-Sector Permit) can be used to evaluate thesignificance of the chemical concentrations in NBSD’s storm water discharge to San Diego Bay.

The Multi-Sector Permit, Sector R, includes requirements for Ship and Boat Building or RepairYards. According to the Multi-Sector Permit (p. 64766-69), when the industrial storm waterdischarge has concentrations greater than the USEPA Benchmark Values (p. 64767, Table 3), theindustrial facility is required to increase monitoring frequencies. Additionally, the Multi-SectorPermit states that the facility operators should review and modify their storm water pollutionprevention plans (SWPPP) and best management practices (BMP) at their facility to try toimprove the quality of the storm water discharge when discharge concentrations are greater thanthe USEPA Benchmark Values. The USEPA Benchmark Value for copper concentrations is 63.6µg/L. The USEPA Benchmark Value for zinc is 117 µg/L.

While the USEPA Benchmark Values are not an enforceable numeric limit, they are used toindicate concentrations of concern and to alert the regulated discharger to take actions to lowerthe concentrations in its discharge. When comparing the chemical concentrations identified inthe NAVSTA storm water discharges to the USEPA Benchmark Values, some of the copper andzinc concentrations were significant.

The CNRSW has submitted monitoring reports pursuant to the General Industrial Storm WaterPermit. From a review of the monitoring reports, copper and zinc concentrations at theNAVSTA are of concern. As shown in Table 6. Naval Station, San Diego, Industrial StormWater Discharge Analyses, 1999/2000 and 2000/2001, the copper and zinc concentrations in thestorm water discharges at the NAVSTA often exceed the USEPA Benchmark Values for copper(63.6 µg/L) and zinc (117 µg/L). Some industrial storm water discharges from the NAVSTA hadsignificantly higher concentrations. There were 21 outfalls sampled for copper and zincconcentrations in the wet weather season 2000/2001.

The discharge of industrial storm water containing copper concentrations greater than 63.6 µg/Land zinc concentrations greater than 117 µg/L are a significant concern.

Storm water monitoring data submitted by other industries located along San Diego Bay can beused to evaluate the significance of the chemical concentrations in NAVSTA’s storm waterdischarge to San Diego Bay. The commercial shipyards are subject to NPDES permits thatrequire monitoring of storm water discharges (e.g., Order No. 97-36, and Order No. 97-37).

The NAVSTA industrial storm water discharges with copper or zinc concentrations significantlygreater than the USEPA Benchmark Values are not expected to achieve a 90% survival rate whenthe undiluted industrial storm water is subject to toxicity analyses using standard test species andmethods. Data for a comparison of the NBSD copper and zinc concentrations and toxicity can befound in three reports; Analysis of Administrative Civil Liability for Complaint No. 2001-24,National Steel and Shipbuilding Company; Analysis of Administrative Civil Liability forComplaint No. 2001-138, SouthWest Marine; and Analysis of Administrative Civil Liability forComplaint No. 2001-113, Continental Maritime.

The storm water monitoring data from the NAVSTA and from the shipyards in the San DiegoRegion indicates that the concentrations of copper and zinc in the storm water from theNAVSTA are toxic. The Order requires that industrial storm water discharges from theNAVSTA achieve a toxicity survival rate of 90% survival, 50% of the time and not less than70% survival, 10% of the time. The Order allows the NAVSTA four years from the adoption



date of the Order to achieve the specified toxicity survival rate. For the interim period, thespecified toxicity survival rate is a performance goal.

The industrial storm water discharge toxicity requirement and monitoring program is similar tothe requirements included in the NPDES permits for the commercial shipyards in the San DiegoRegion and for the Naval Base Point Loma.

Order No. R9-2002-0169 includes monitoring requirements for determining the quality of theindustrial storm water discharges and requires the discharger to perform an evaluation of thedischarges. Whenever the analyses of an industrial storm water discharge from a particularcatchment basin contains a copper concentration greater than 63.6 µg/L or a zinc concentrationgreater than 117 µg/L, the Order requires the discharger to perform the following tasks:

a) review and modify the SWPPP as necessary to reduce the concentrations of copper and zinc;b) after modifying the SWPPP, sample and analyze the next two storm water runoff events;c) document the review and the modifications to the SWPPP, and document the sampling

analysis.

IV. RATING

Pursuant to the NPDES Permit Rating Worksheet, the proposed discharge from the Naval BaseSan Diego has a point score of 529.5. The Point Score includes a rationale to make the facility adiscretionary major. The rationale for a discretionary major classification is that the facilityincludes a large area and includes significant industrial storm water discharges.

Accordingly, the NBSD Complex is classified as an NPDES Major Discharger. Pursuant toTitle 23, Section 2200 of the California Code of Regulations, the discharger has been identifiedas having a Threat to Water Quality and Complexity (TTWQ/CPLX) rating of 1/A.

V. BASIS FOR CONDITIONS IN THE WASTE DISCHARGEREQUIREMENTS (WDR)

a. Beneficial Uses for San Diego Bay

The Basin Plan (p. 2-47, Table 2-3. Beneficial Uses of Coastal Waters) established the followingbeneficial uses for the waters of San Diego Bay:

a. Industrial Service Supply;b. Navigation;c. Contact Water Recreation;



d. Non-contact Water Recreation;e. Commercial and Sport Fishing;f. Preservation of Biological Habitats of Special Significance;g. Estuarine Habitat;h. Wildlife Habitat;i. Rare, Threatened, or Endangered Species;j. Marine Habitat;k. Migration of Aquatic Organisms; andl. Shellfish Harvesting.

b. Enclosed Bays and Estuaries Policy, Nonmunicipal Waste Discharges

The State Water Resources Control Board (hereinafter State Board) adopted a Water QualityControl Policy for Enclosed Bays and Estuaries of California (Bays and Estuaries Policy) onMay 16, 1974. The Bays and Estuaries Policy establishes principles for management of waterquality, quality requirements for waste discharges, discharge prohibitions, and general provisionsto prevent water quality degradation and to protect the beneficial uses of waters of enclosed baysand estuaries. These principles, requirements, prohibitions, and provisions have beenincorporated into this Order.

The Bays and Estuaries Policy contains the following principle for management of water qualityin enclosed bays and estuaries, which includes San Diego Bay:

The discharge of municipal wastewaters and industrial process waters (exclusive ofcooling water discharges) to enclosed bays and estuaries shall be phased out at theearliest practicable date. Exceptions to this provision may be granted by a RegionalBoard only when the Regional Board finds that the wastewater in question wouldconsistently be treated and discharged in such a manner that it would enhance the qualityof receiving waters above that which would occur in the absence of the discharge. Forthe purpose of this policy, treated ballast waters and innocuous nonmunicipalwastewater such as clear brines, washwater, and pool drains are not necessarilyconsidered industrial process wastes, and may be allowed by Regional Boards underdischarge requirements that provide protection to the beneficial uses of the receivingwater.

As explained in the Point Source Discharge section, the point source discharges, other thanindustrial storm water runoff, can be considered to be innocuous because of the nature of thedischarges or the volume of the discharges. If a significant or material change occurs in thedischarges (i.e. chemical concentrations, physical properties, location, volume, or frequency), thepotential impact to beneficial uses may change or cause a violation of the Order No. R9-2002-0169. Any change in either the nature or volume of the discharges can be readily identified andevaluated through the monitoring requirements specified in Monitoring and Reporting ProgramNo. R9-2002-0169.



For the purpose of the Bays and Estuaries Policy and Order No. R9-2002-0169, the discharge ofthe following wastes will be considered innocuous nonmunicipal wastewaters and, as such, willnot be considered industrial process wastes:

• Utility Vault & Manhole Dewatering;• Steam Condensate;• Salt Water System;• Pier Boom, Mooring, and Fender System Cleaning; and• Miscellaneous Discharges (landscape watering runoff, potable water & fire system

maintenance).

Therefore, the discharges of such wastes may be allowed by the Regional Board under wastedischarge requirements that provide protection of the beneficial uses of the receiving waters.Order No. R9-2002-0169 includes requirements, prohibitions, provisions, and monitoring thatprotect the beneficial uses of the receiving waters.

c. California Toxics Rule and Implementation Policy

On May 18, 2000, the U.S. Environmental Protection Agency (USEPA) promulgated theCalifornia Toxic Rule (CTR), 40 CFR 131.38. The CTR restored California’s water qualitystandards for inland surface waters. The previous inland surface waters plan, which containedwater quality criteria for priority toxic pollutants, was dismissed in 1994 when a State courtoverturned the State Board’s plan.

The water quality criteria established in the CTR, 40 CFR 131.38, is legally applicable in theState of California for inland surface waters, and enclosed bays and estuaries for all purposes andprograms under the Clean Water Act.

On March 2, 2000, the State Board, in Resolution No. 2000-15, adopted a Policy forImplementation of Toxic Standards for Inland Surface Waters, Enclosed Bays, and Estuaries ofCalifornia (Implementation Policy). The Policy implements the criteria for the 126 prioritypollutants in the CTR. The State Board’s Policy became effective on April 28, 2000, as appliedto the National Toxics Rule and to the CTR.

The Policy establishes:

a) implementation provisions for priority pollutant criteria promulgated by theUSEPA through the National Toxic Rule (NTR) and the CTR, and for prioritypollutant objectives established in the Basin Plan;

b) monitoring requirements for 2,3,7,8-TCDD (tetrachlorodibenzo-p-dioxin)equivalents; and

c) chronic toxicity control provisions.



MRP No. R9-2002-0169 requires the discharger to conduct an initial sampling of the dischargesand the receiving waters for the priority pollutants and dioxin congeners as specified in theImplementation Policy. The discharger shall conduct one initial sample analyses of the dischargefor the pollutants listed in the Implementation Policy.

The discharger is required to conduct sampling analyses of the following discharges andreceiving waters:

• Salt Water;• Steam Condensate;• Pier Boom, Mooring, and Fender System Cleaning; and• Miscellaneous.

Once the monitoring for the priority pollutants is submitted to and evaluated by the RegionalBoard, the Regional Board may either:

• request additional priority pollutant monitoring pursuant to Section 13267 of the Porter-Cologne Water Quality Control Act;

• determine that there is no reasonable potential for the discharge to cause an exceedence ofthe water quality criteria; or

• reopen the Order and recommend discharge limits for priority pollutants in the dischargethat have a reasonable potential to cause an exceedence of the water quality criteria.

Pursuant to Section 1.4.4 Intake Water Credits (p.17) of the Implementation Policy, a RegionalBoard may consider priority pollutants in the intake water on a pollutant-by-pollutant anddischarge-by-discharge basis when establishing water quality-based effluent limitations. Certaindischarges from the NBSD may qualify for Intake Water Credits.

d. 303(d) List

In February 1998, the Regional Board included portions of San Diego Bay as an impaired waterbody pursuant to the Clean Water Act, Section 303(d). Three of these locations are at theNAVSTA, the Broadway Complex, and at the mouth of Chollas Creek. The listing was theresult of information gathered for the Chemistry, Toxicity and Benthic Community Conditions inSediments of the San Diego Bay Region, Final Report, September 1996 (commonly know as thereport for the Bay Protection and Toxic Cleanup Program (BPTCP)). The data gatheredpursuant to the BPTCP caused the Regional Board to declare 76 acres of the NAVSTA area, 10aces near the Broadway Street pier, and 14 acres near the mouth of Chollas Creek impairedbecause of benthic community effects and sediment toxicity.



e. Metals

The metal concentrations in the industrial storm water discharges from NAVSTA are significantand are a potential impact to water quality and beneficial uses of San Diego Bay.

Industrial storm water discharge requirements and specifications, and storm water monitoringand reporting requirements are included in Order No. R9-2002-0169. The requirements aredescribed in the Industrial Storm Water section of this Fact Sheet.

At the April 10, 2002 Regional Board meeting for the Order for discharges from the Naval BasePoint Loma (NBPL), the U.S. Navy indicated they are currently conducting storm watermonitoring for a total maximum daily load (TMDL) at the 32nd Street Naval Station, they haveparticipated in the BPTCP, and they have existing sediment-monitoring programs.

The Order does not require monitoring of sediments. The Navy will work with the RegionalBoard’s total maximum daily load (TMDL) program to monitor the sediments.

f. Toxicity

The Basin Plan includes the following narrative as a water quality objective, which is applicableto the discharge:

Water Quality Objectives for Toxicity:

All waters shall be maintained free of toxic substances in concentrations that are toxic to, or thatproduce detrimental physiological responses in human, plant, animal, or aquatic life.Compliance with this objective will be determined by use of indicator organisms, analyses ofspecies diversity, population density, growth anomalies, bioassays of appropriate duration, orother appropriate methods as specified by the Regional Board.

The survival of aquatic life in surface waters subjected to a waste discharge or othercontrollable water quality factors, shall not be less than that for the same water body in areasunaffected by the waste discharge or, when necessary, for other control water that is consistentwith requirements specified in U.S. EPA, State Water Resources Control Board or other protocolauthorized by the Regional Board. As a minimum, compliance with this objective as stated in theprevious sentence shall be evaluated with a 96-hour acute bioassay.

In addition, effluent limits based upon acute bioassays of effluents will be prescribed whereappropriate, additional numerical receiving water objectives for specific toxicants will beestablished as sufficient data become available, and source control of toxic substances will beencouraged.



Toxicity monitoring for the point source discharges is not necessary. Toxicity monitoring for thestorm water discharges is explained in the Industrial Storm Water Discharges section of this FactSheet.

g. Prohibitions

As noted previously, the Basin Plan and the Enclosed Bays and Estuary Policy directly apply tothe proposed discharge. The applicable prohibitions from the Basin Plan, and the Enclosed Baysand Estuary Policy are incorporated into the Order and MRP.

h. Public Hearing

Order No. R9-2002-0169 is scheduled to be considered by the San Diego Regional Board at apublic hearing on:

November 13, 2002, beginning at 0900 at the following location:
